COUPLING FOR COMPOUND PROFILE MEMBERS FOR DOORS OR WINDOWS

Description

[0001] My invention relates to a coupling system of profiles for door and window frames by means of a rotating, profile connection key, respective profile connection key and frame.

[0002] The invention finds a particular even if not exclusive application as a fixation system for wood profiles, for coating internally window and door frames in aluminium.

Background Art

[0003] In the prior art, it is known that to fix wood and aluminium profiles are used rotating, profile connection keys.

[0004] Examples of these systems have been disclosed in the documents FR,A,2516122 (ZAPP), AT,B,308361 (SOMMER) and PCT/IT90/00090 (ARCHIMEDE PROGETTI).
The first two solutions reveal a profile connection key with two opposite key-shaped tapered flanges, with a central connection neck able, by means of the two opposite tapers of the flanges, to consent the coupling of profiles with a direct axial insertion (orthogonal in respect to the groove of the profile) with a successive connection by rotating 90° the same profile connection key.

[0005] The third solution provides instead, on one side, a key-shaped tapered flange and on the other a disc-shaped flange, which must be previously inserted head first inside one of the grooves of the profiles, to then couple the second profile by means of a direct orthogonal coupling and a successive rotation of 90° of the profile connection key.

[0006] These solutions even if they give us the possibility to couple two profiles generally inside the respective dovetail or undercut groove, have the drawback that they are free to scroll inside the respective groove or have a slight interference, consequently:

• if with interference on one side and free scrolling on the other, once inserted in the groove on the side of profile without interference, it is not possible to keep them in a position for the coupling with the second profile unless we make a horizontal assembly, having to, during the assembly or vertical re-assembly proceed to the re-spacing and fixation one at a time;
• if they have interference on both sides, these present from the start, a difficulty in positioning for slippage.

Disclosure of Invention

[0007] The object of the present invention is to obviate the above-mentioned drawbacks.

[0008] This and other scopes are reached as claimed by means of a coupling system for profiles of door and window frames, utilising a plurality of profile connection keys spaced along the profile, the profile connection keys having a key hooking head on one side and a disc-shaped flange on the other, connected by a neck with an intermediate key shaped spacer (key to allow rotation of the entire device for keying two separate pieces), characterised in that the disc-shaped flange has a modified disk-shaped form with an elastic interference protrusion on two orthogonal crossing axes respectively, the point where they cross coinciding with the longitudinal axis of said key hooking head.

[0009] The method is characterised more particularly in that:

• said disc-shaped flange is free to slide when seated inside the groove of the first profile with the orthogonal axes rotated in respect to the initial position, up to a maximum of 45°, in order that it is possible, after having inserted the disc-shaped flange of the profile connection key inside said first profile and having rotated it 45° in respect to the interference axes in the first profile, to permit said profile connection key to move up and down freely inside the respective groove of the first profile,
• each profile connection key, once in a coupling position, is rotated 45° in order that the free protruding key hooking head is disposed longitudinally in respect to the groove of the first profile, resting there resiliently held by the interference protrusions, allowing insertion of the key hooking head in the second profile, and rotating each profile connection key 90°, to bring the disc-shaped flange to rest in a second stable interference position.

[0010] In this way we obtain the advantage to have the possibility to:

• move freely the profile connection keys along the groove of the first profile,
• place them exactly in the position wanted, and lastly,
• rotate them 90° after having inserted transversely the second profile on them, for the definitive coupling.

[0011] With these operations, thanks to the interference system according to an angle of rotation with free slippage at an angle of rotation different if associated to the position of the connection of the second flange with the second profile, it is possible to carry out the assembly and disassembly of wood lathes, for example for replacement, in any position, also vertically and so also on frames of doors and windows already installed vertically on the wall, without the danger and difficulty of misplacing the respective profile connection keys.

[0012] These and other advantages appear in the successive preferential solution description of realisation with the help of the enclosed drawings of which execution details are not to be considered limitative but only supplied for example.

[0013] Figure 1 represents a frontal view of a profile connection key from the side of the connecting flange on the first profile, modified disc-shaped.

[0014] Figure 2 represents a side view of the left side of the profile connection key of figure 1 with the respective profiles to couple respectively, the first in aluminium on the right and the second in wood on the left.

[0015] Figure 3 represents a view from above, of the profile connection key of figure 1.

[0016] Figures 4, 5, 6 represent the three views of a profile connection key with a right angle rotation for the fixation of the frame to the case on the wall.

[0017] Figure 7 represents a section of a profile of a frame assembled to realise a window frame.

[0018] Making reference to the Figures it is disclosed that the invention consists substantially in a coupling system for profiles of door and window frames, utilising a plurality of profile connection keys (A) spaced along the profile (C), the profile connection keys (A) having opposite flanges which are connected to the profiles by rotation after their insertion in the respective profile grooves, with a rectangular key hooking head on one side (1) having its respective borders from 11-111 tapered and having a rounded corner (11) and a sharp corner (111), and with a disc-shaped flange on the other (4), connected by a neck (3) with an intermediate key-shaped spacer (2), characterised in that the disc-shaped flange (4), has a modified disk-shaped form:

• with elastic interference protrusions (42) on two orthogonal crossing axes (X/Y) respectively, the point where they cross coinciding with the longitudinal axis of said key hooking head (1).
• with free slippage, even if always locked inside the groove of a first profile (C), on an orthogonal axis rotated, in respect to the previous position, up to a maximum of 45° (Z1/Z2), in order that it is possible,
• after having inserted the disc-shaped flange of the profile connection key (4) inside the same first profile (C) and rotated 45° in respect to the interference position in the first profile (Z1/Z2),
• to consent said profile connection keys (A) to scroll freely inside the respective groove of the first profile (C) and:
• once in a coupling position, to be rotated 45° in order that the free protruding key hooking head (1) is disposed longitudinally in respect to the groove of the first profile (C), resting there resiliently held by the interference protrusions, allowing insertion of the key hooking head in the second profile (B/ B') and lastly:
• rotate each profile connection key (A) 90°, to bring the disc-shaped flange to rest in a second stable interference position.

[0019] Advantageously the respective bulges of the connection key which form the interference protrusions are made by means of hollows (41) that form a pair of serrations (42) slightly protruding to form an elastic interference (i).

[0020] The door or window frame is secured to the case on the wall by means of right-angled pieces (A1) that have on one side a rotating disc-shaped flange (51) with connection neck (52) along a profile of the frame (C) and on the other at least one hole (56) for a screw means (V) of fixation.

[0021] In this way the positioning is easy and sure and the same right-angled piece (53) disposes of a respective resiliently yielding fin (54) with a serration (55) in order to consent the transversal automatic spring connection of a butt strap (E) in association with the coinciding groove (B1) and abutment E1 on an adjacent wood strip (B') inserted with profile connection keys (A) as before, (B).
